l Specification of Letters Ilatenit. i Applicationled August 2, 1911.SerialNo;642,015'.r ,f Y f To all whom 'it may concern:

Be it known that I, JAMES PATTERSON, a citizen of the United States,residing at Rockwell, in the county of Marion and State of Florida, haveinvented new and useful Improvements in Rail-Clamping Devices, of whichthe following is a specification.

An object of the invention is to' provide a devicefor'rigidly clampingrails to railway ties.

My invention embodies among other features, a structure in which theclamping members thereof can be adjusted so that the force clamping therail to the tie' can be increased or decreased, my device being so ar'-ranged that a rail can be easily and quickly `disconnected from a tiefor the purpose of repairing the same or inserting a new rail.

To accomplish the desired result, use is made of atie provided'with arecessed end flange in-which the rail is adapted to seat with one sideof the webof the rail abutting against' the end of the flange, slottedside flanges formed on the tie, a clamping bar pivotally mounted in theslots of the side flanges and adapted to engage the other side of theweb of the rail, a wedge for insertion in the slots of the said sideflanges and having one side thereof abutting againstl the clam-ping bar,the other side of the wedge being 1n engagement with a bracev formed onthe tie and means for operating the said wedge for increasing ordecreasingI the clamping engagement of bar with the said rail.

Reference is to be had to the accompanying drawings constituting a partof this specification, in which s1milar characters of reference denotecorresponding parts in all the views and in which- Figure 1 is aperspective view of one o f my ties, showing the same in applied pos1-the clamping f tion. Fig. 2 is a vertical longitudinal section throughthe tie, taken substantially on the line 2-2 in Fig. 1. Fig. 3 is avertical sectional view taken on the line 3-3 in Fig. 1. Fig. 4 is avertical sectional view taken on the line 4-4 in Fig. 1. Fig. 5 is afragmentary sectional view taken on the line 5-5'in Fig. 1.

Referring more particularly to the views, I provide a tie 10 having endflanges 11 provided with recesses 12, rails 13 being adapt-A ed torestjon a base 14 of the tie 10 with portions of the bases of the railsreposing within the recesses 12 and tvith one ofthe websfof each of therails :itintting against the inner face of each of thelanges 11.-

Formed on the tie 10 and projecting outwardly from the sides thereof areside flanges 15 provided with vertically extending' slot-s 16 and anupwardly extending brace 17 is formedat one end of the-side flanges 15`and extends transversely to the vtie 10. A clamping bar 18, consistingof a head 19 and spaced depending extensions 20,2 1s mounted on the sideflanges 15 with the extensions' 20 passing through the slots 16, a bolt21 being passed transversely through the tie 10v and throughapertures'in the extensions 20 to pivot-ally retain the clamping bar -18in engagement with the` tie 10. thehead- 19 of the clamping bar bemg`adapted to engage one side of the web of each of the rails 13. A wedge22.I consisting of a head 23 and spaced extensions 24 is mounted betweenthe brace 17 and-the clamping bar 18 with the extensions 24 of vthewedge passing through the slot 16 of the side flanges 15. A set screw 25is mounted to extend through the brace 17 `to engage a sideof the head23 of the wedge 22 and a second set screw 26 is mounted to extendthrough one of the side flanges 15 to engage one of the extensions 24 ofthe said wedge 22.

In the use of my device, 'the set screws 25 and 26 are moved out vofengagement with the Wedge 22 so that the clamping bar 19 can be moved tounclamping position andthe rail 13 is then extended across the tie 10with the base of the railreposingl idly secure the same to the tie 10,it being understood that a side 27 of the headf19 will lie against oneside of the base of the rail.

With the use of the device described in connection with rails, the saidrails'will be retained inrigidposition relatively to the ties and` canbe easily` and quickly removed from the ties, while at the'same timewhen the rails are rigidly. clamped to the ties anyv lrail with one sideof the web of the rail abut-ting against the said end flange, sideflanges formed on the said tie and provided with slots, a braceextending transversely to the tie at one end of the said side flanges,

Va clamping bar pivotally mounted on the said tie with portions of thesaid clamping bar extending through the slots in the said side flangesand another portion of thesaid clamping bar for engagement with theother side of theweb of the rail, a wedge for engagement with the saidbrace and said clamping bar andset screws mounted to extend through thesaid brace and through one of the said side flanges to engage the saidwedge for operating the same to move the said clamping bar into clampingengagement with the said rail.

2. A rail clamping device comprising a tie,'an end flange formed on thetie and provided With a recess adapted to receive the rail with one sideofthe web of the rail abutting against the said end flange, side flangesformed on the said tie and provided with slots, a brace extendingtransversely to the tie at one end of the said side flanges, a clampingbar pivotally mounted on the said tie with portions of the said clampingbar extending through the slots in the said side flanges and anothervportion of the said clamping bar for engagement with the other side ofthe web of the rail, a wedge for engagement with the said brace and saidclamping bar and adjusting means mounted on the said tie for operatingthe said wedge to move the said clamping bar into clamping position withthe said rail.

3. A rail clamping device comprising a. tie, an end flange on thesaidtie, side flanges.

on the said tie, a clamping bar pivotally mounted on the said tie andengaging the said side flanges, a head on the said clamping bar forengagement with a rail mounted to abut against the said end flange andav ing bar for engagement with a rail mounted to abut against the saidend flange and means mounted on the said tie and engaging the saidclampingbar for retaining the said clamping bar in clamping-engagementwith the said rail.

5. A rail clamping device comprising a tie, an end flange on the saidtie and adapted to be engaged by .a rail, a clamping bar mounted toswing on the said tie and capable of being moved into. clampingengagement with the said rail, a wedge for engagement with the said tieand the said clamping bar andl set screws to move the said clamping barinto clamping engagement with the sai rail.

6. A rail clamping device comprising a tie, an end flange on the saidtie and adapted to be engaged by a rail, a clamping bar mounted to swingon the said tie and capable of being moved into clamping engagement withthe said rail, a wedge for engagement with the said tie and saidclamping bar and means for operat-ing the said wedge to move the saidclamping barvinto clampingv engagement with the said rail.

7. A rail clamping device comprising a tie, an end flange on the saidtie and adapted to be engaged by a rail, a clamping bar mounted to swingon the said tie and capable of'being moved into clamping engagement withthe said rail and means engagingthe said'tie and the said clamping barfor retaining the said clamping barin clamping engagement with the saidrail.

In testimony whereof I afiix my signature in presence of two witnesses.
